Sync Video to Audio

i'm a beginner in flash (cs 5.5) and just can't find a solution for the following issue:

basically i want to make a music-video, so audio is already specified (10min-file). now it's just a matter of editing the whole thing, as i want to animate different objects fitting the audio. if played from start everything's fine, but if i just choose to play from frame 2 (audio starts in frame 1) audio will not play and thus makes it nearly impossible to achieve the result i'm looking for, as i need precision down to one frame to make animations fit perfectly.
